How long would a 60 watt light bulb have to burn to produce the energy you used climbing the stairs?

If you weigh 70 kg and the stairs are 3 metres high, the energy needed is 70 x 9.8 x 3 Joules or 2058 joules. That would keep a 60 w bulb going for 2058/60 seconds, or 34.3 seconds.
But to produce that same energy in a generating plant, the fuel energy wasted in the process would be between 2000 joules for a gas plant of 50% efficiency, and 6000 joules for a coal plant of 25% efficiency.
